Observational Study
[Ketamine i. v. for the treatment of cluster headaches : An observational study].
Cluster headaches have an incidence of 1-3 per 10,000 with a 2.5:1 male-to-female gender ratio. Although not life threatening, the impact of the attacks on the individual patient can result in tremendous pain and disability. The pathophysiology of the disease is unclear, but it is known that the hypothalamus, the brainstem, and genetic factors, such as the G1246A polymorphism, play a role. ⋯ In a controlled setting, we treated 29 patients with cluster headaches (13 with chronic cluster and 16 with the episodic form), who had been refractory to conventional treatments, with a low dose of ketamine (an NMDA receptor antagonist) i.v. over 40 min to one hour every 2 weeks or sooner for up to four times. It was observed that the attacks were completely aborted in 100 % of patients with episodic headaches and in 54 % of patients with chronic cluster headaches for a period of 3-18 months. We postulated neuroplastic brain repair and remodulation as possible mechanisms.

The monitoring of facial expressions to assess pain intensity provides a way to determine the need for pain medication in patients who are not able to do so verbally. ⋯ Results show that the facial expression analysis based on FACS represents a credible method to detect pain. Because of the expenditure of time and personal costs, FACS cannot be used properly until automatic systems work accurately. The use of EMG seems to be helpful in the meantime to enable continuous pain monitoring for patients with acute post-operative pain.

The practical year (PY) during the final year of medical education is intended to deepen and broaden knowledge, skills, and abilities that were acquired during previous years of their studies. Against this background, this study pursues the question of how the knowledge of future physicians and their confidence in terms of cancer pain therapy and other palliative care issues develops during the PY. ⋯ In the present study, considerable deficits in confidence and knowledge regarding palliative care issues were also observed at the end of PY. Integration of palliative care into the medical school curriculums should be given special attention in terms of a longitudinal training of the PY.
